Short answer: brewed green tea is close to neutral and effectively neutral by acid load too, and it is not on Dr. Sebi's list of approved teas.
The guide names seven herbal teas and green tea is not one of them. Neither is matcha, which is the same plant.
The numbers
Brewed green tea typically measures somewhere around pH 7 to 8, making it one of the few drinks that is not acidic in the cup at all. That is genuinely unusual — most things people drink sit well below neutral.
On acid load, published PRAL tables put tea at about −0.3. Effectively neutral. Herbal infusions of any kind are mostly water, and their main effect on your day is displacing whatever you would otherwise have drunk.
So green tea measures well. Its absence from the guide is not about acidity.
Where it sits on the guide
The nutritional guide names seven herbal teas: burdock, chamomile, elderberry, fennel, ginger, raspberry and tila. All seven are caffeine-free.
Green tea, black tea, white tea, oolong and matcha are all Camellia sinensis — the same plant, processed differently — and none of them appear. Nor do the other popular herbals people assume must be fine: peppermint, rooibos, hibiscus, lemon balm, dandelion root and chicory are all outside the seven.
The guide works as a closed list. If something is not named, it is not on it, and there is no category rule to reason from.
What green tea brings that the approved teas don't
Mostly caffeine. A cup of green tea carries roughly 25 to 45mg, depending on leaf, water temperature and steeping time — around a third of a cup of coffee. Matcha is higher, because you drink the leaf rather than an infusion of it.
If green tea is your mid-afternoon habit, that caffeine is doing more of the work than the ritual is, and it is worth knowing before you swap. The seven approved teas will not replicate it.
What to drink instead
Match the job rather than the leaf.
- For the morning lift: strong simmered ginger, or roasted burdock root. Neither is caffeinated, but both are assertive enough to feel like a proper drink rather than hot water.
- For the grassy, slightly bitter character: burdock is the closest on the list. It is earthy rather than vegetal, but it scratches the same itch.
- For something light through the day: fennel or chamomile, both mild enough to drink repeatedly.
- For the evening wind-down: chamomile or tila.
- For a cold drink: brew ginger or raspberry strong, cool it, and keep it in the fridge with key lime. Iced herbal tea is badly underrated and replaces both green tea and soft drinks.
Brew them properly
This is the difference between a pleasant drink and hot water with a tea bag in it.
Roots and barks are simmered, not steeped. Burdock, ginger and sarsaparilla go into cold water, come to a boil, and hold at a simmer for fifteen to twenty minutes with the lid on. That is a decoction.
Leaves and flowers are infused. Chamomile, raspberry leaf and tila get boiling water poured over them, covered, for ten to fifteen minutes. Covering matters — the aromatics you want leave in the steam otherwise.
Loose is stronger than bagged. A squeeze of key lime is on the guide; honey is not.
If you drink green tea supplements
This is worth separating clearly, because the beverage and the extract are not the same thing.
The NIH's LiverTox database states plainly that "drinking green tea has not been associated with liver injury or serum aminotransferase elevations." Green tea as a drink has a clean record.
Concentrated green tea extract is different. LiverTox notes that extract, and more rarely very large quantities of the beverage, have been implicated in cases of clinically apparent acute liver injury. The cases involve concentrated supplements, particularly in weight-loss products, and the injury appears idiosyncratic rather than dose-driven — closely associated with the HLA allele B*35:01, which you have no way of knowing you carry.
If you take a green tea or EGCG capsule, that is the one to raise with your doctor. The cup of tea is not the concern.
Other things worth knowing
- Iron absorption. Tannins in tea reduce non-haem iron absorption, which matters on a plant-based list. Drink tea between meals rather than with them, and leave an hour either side of an iron-rich meal or supplement.
- Caffeine and sleep. Caffeine's half-life is around five hours, so a 4pm cup still has half its caffeine working at 9pm.
- Pregnancy. Caffeine intake is usually limited in pregnancy; and note that raspberry leaf, one of the approved seven, is traditionally a late-pregnancy tea rather than an any-time one. Worth a word with your midwife.
Common questions
Is matcha on the list?
No. Matcha is green tea leaf ground whole, same plant, and it is not among the seven.
Is green tea alkaline or acidic?
Close to neutral in the cup at around pH 7 to 8, and effectively neutral by acid load at about −0.3 PRAL.
What about decaf green tea?
Still not on the guide. The exclusion is of the tea, not the caffeine.
Is peppermint tea approved?
Not among the seven. Nor are rooibos, hibiscus, lemon balm, dandelion root or chicory — the last two catch people out because they are recommended so often as alkaline coffee substitutes. Burdock is the one on the list.
Does green tea break a fast?
Unsweetened, it is a couple of calories and won't disturb a normal window. The longer answer is here.
How many cups of the approved teas can I drink a day?
There is no stated limit, but rotate rather than drinking litres of one thing. Several of the herbs have their own cautions — set out on the herbs page — and variety is the simplest way to stay clear of them.
